STUDENT S TYPEWRI'IER DESK Filed April 21, 1966 2 Sheets-Sheet 2 United States Patent 3,313,249 STUDENTS TYPEWRlTER 131351; Gliver M. Marcy, Webster Lake, West Franklin, NH. 03235 Fiied Apr. 21, 1966, Ser. 1 o. 544,264 2 Qlaims. (61. 108-124) This invention comprises a new and improved typewriter desk particularly well suited for students use. It is therefore constructed and arranged to be of low manufacturing cost, light in weight, stilt and sturdy in use and collapsible for purposes of convenient transportation and storage.

With these features in view my novel desk includes a rear panel, hinged side panels and a lid so connected that they may be folded in superposed collapsed position or erected and rigidly interlocked without the use of tools or loose fastening elements.

The lid is hinged to the back panel and arranged to rest directly and solidly at each edge upon the side panels and to interlock therewith in such a manner as positively to prevent separation, thus imparting a solidarity to the whole structure which is intensified by the weight of a typewriter on the lid of the assembled desk.

In order to provide for collapsing the elements of the desk the lid is hinged to the back panel to swing 270 from its normal horizontal position to a vertical position in contact with the rear or outer face of the back panel. The side panels are also hinged to the back panel so that they may be folded into overlapping relation upon the inner face of the back panel.

These and other features of the invention will be best understood and appreciated from the following description of a preferred embodiment thereof selected for purposes of illustration and shown in the accompanying drawings in which:

FIG. 1 is a view in perspective of the assembled desk,

FIGS. 2 and 3 are fragmentary views showing the connecting structure of the elements of the desk, and

FIG. 4 is a fragmentary sectional view showing the elements in collapsed position.

The desk comprises four panels of plywood or other stiff sheet material such as a good grade of wallboard. As herein shown the upright rear panel is substantially rectangular in shape except it has a concave lower edge. Side panels 11 and 12 are hinged by hinges 11 and 12' to the opposite edges of the rear panel 10 and these hinges are so located that, when the components of the desk are collapsed, the rear panel is suspended with its lower edge ten or twelve inches above the floor. panels therefore are arranged to swing from their parallel upright position as shown in FIG. 1 into collapsed overlapping position as shown in FIG. 4.

The lid 13 is substantially rectangular and is hinged at its rear edge to the back panel 10 by L-shaped hinges 18 as suggested in FIG. 2 which are so proportioned as to permit the lid 13 to make the full 270 swing above described. The lid is formed at each side with a receptive The side reentrant notch 19 arranged to make interlocking engagement with an angular tongue formed in each of the side panels. The lid 13 spans the erect side panels and is thus provided at its outer edge with areas that make solid and direct contact with the side panels. The notches and tongues also form mating beveled areas of contact so that the side panels 11 and 12 are positively interlocked against inward or outward swinging so long as the lid 13 is in horizontal position as shown in FIG. 3. It will be seen that the weight of the typewriter upon the lid tends to hold it all the more firmly in its assembled relation. At the same time when the typewriter is removed the lid is free to be swung upwardly about its hinges 18 so that the side panels are at once released for movement into their collapsed position.

The lid 13 is provided with a hand hole 14 near its rear edge in position to register with a hand hole 15 which is formed near the upper edge of the rear panel 10. Similarly the side panel 11 is formed with a hand hole 16 and the side panel 12 has a hand hole 17 and these are so located as to register when the four elements are folded into their collapsed position as shown in FIG. 4 thus affording convenient means for the collapsed desk to be picked up and transported to any location. The general decorative design of the several elements is not only pleasing to the eye, but correct from the mechanical standpoint.

Having thus disclosed my invention what I claim as new and desire to secure by Letters Patent is:

1. A student's typewriter desk comprising an upright back panel, side panels hinged to opposite sides of the back panel and extending forwardly in parallel relation from the back panel, and a lid hinged to the back panel and provided in each edge with a reentrant notch arranged to interlock with an angular tongue formation of the adjacent side panel thereby holding the side panels against separation and supporting the lid by direct contact outlwardly beyond said notch.

2. A students typewriter desk as described in claim 1, further characterized in that the back and side panels are of plywood and have hand holes adjacent to their upper edges that register with a hand hole in the lid when the panels and lid are folded into superposed collapsed position.
